Abstract

The invention relates to the technical field of monitoring of environment protection pollutants and in particular relates to a detection system and method for heavy metal in water. The detection system comprises a cabin body, and a sample platform, a laser excitation device, a light spectrum collection and analysis device and an enrichment substrate assembly which are located in the cabin body, wherein the enrichment substrate assembly comprises a base and chelated resin particles attached to the bottom surface of the base; the enrichment substrate assembly which finishes adsorption of the heavy metal in a water body sample to be detected is put on the sample platform; the laser excitation device is located above the sample platform to generate a laser beam for hitting and firing the surfaces of the chelated resin particles of the enrichment substrate assembly; the light spectrum collection and analysis device is used for carrying out acquisition and online analysis on a plasma signallight spectrum obtained by surface gasification of the enrichment substrate assembly. According to the detection system and method, provided by the invention, heavy metal ions in water are efficientlyenriched through the heavy metal ion enrichment substrate assembly composed of the chelated resin particles; a laser induced breakdown spectrum technology is combined to realize online, rapid and high-sensitivity detection of the heavy metal ions in a water body.

Description

technical field [0001] The invention relates to the technical field of environmental protection pollutant monitoring, in particular to a detection system and method for heavy metals in water. Background technique [0002] With the development of modern industry and agriculture, heavy metals have become one of the most important trace pollutants in the ecological environment. Heavy metals in wastewater generated by industrial production and agricultural pesticides and fertilizers can pollute surface water and groundwater through surface runoff and leaching. They are non-degradable, bio-accumulative, low-level and high-harm, and can seriously endanger human health through the food chain. , known as the most dangerous source of water pollution. Therefore, the realization of rapid detection and quantitative analysis of heavy metals in drinking water is of great significance to national health and national water security. [0003] Routine testing procedures include on-site samp...
